被动防火材料对喷射火灾的抗性试验 第3部分：延长试验要求

[中文适用范围]： 本文件描述了一种扩展的测试方法，用于确定被动防火（PFP）材料和系统或关键过程控制设备抵抗射流火灾的能力。它说明了在严重射流火灾中，PFP 材料或设备的行为，并提供了在规定条件下性能数据。它不包括对其他被动防火材料特性（例如耐候性、老化、抗冲击性、抗冲击性或防爆性）的评估。本文件旨在补充 ISO 22899-1。当所需的火灾条件或测试样品尺寸或类型限制排除了 ISO 22899-1 的应用时，本文件 intended for use in situations when the required fire conditions or limitations on test specimen size or type preclude application of ISO 22899-1. [外文原描述]： This document describes an extended test method determining the resistance to jet fires of passive fire protection (PFP) materials and systems or critical process control equipment. It gives an indication of how PFP material or equipment behaves in a severe jet fire and provides performance data under the specified conditions. It does not include an assessment of other properties of the passive fire protection material such as weathering, ageing, shock resistance, impact or explosion resistance, or smoke production. This document is intended to be complementary to ISO 22899-1. It is intended for use in situations when the required fire conditions or limitations on test specimen size or type preclude application of ISO 22899-1.
